@kmkane... The "old thread" comments, at least from ME... aren't for any other reason than letting some contributors know, that the advice they might believe they are giving, may be moot. I know that when I 1st became involved on Houzz, I was glad when someone indicated that I may be addressing a question which had probably been answered months (if not years) ago. Helped me "learn" to check the original posting date before blathering on about an issue someone was no longer interested in.

I would suggest you take out the cabinet that is to the right of the stove and use it elsewhere in the house -- perhaps in the bathroom or dining room with a hutch above it. Then, I would suggest you have someone install a lazy susan cabinet in the corner between the sink counter and the stove, meaning you would move the stove down a bit and have a small cabinet/counter top to the right of the stove. I would suggest you have the cabinets refinished in white and then paint the walls a pastel you like. If you would prefer white walls, then add white-painted crown molding and paint the ceiling a light neutral blue, such as Sherwin Williams Niagara Falls Blue. Then, I would suggest you choose a favorite accent color and use this sparingly in accessories like towels, pot holders, small vases or floral arrangements, and a valence above the triple windows. For a genuine 1940s look, you might have white ceramic square tiles with a rectangular red border installed as a back splash behind and above the stove. If you are replacing counter tops, I would suggest a light color such as white with a beige or light grey vein or striation for some sort of pattern. You might be able to find the same color and design in floor tile OR opt for a wood floor as another poster suggested.

I don't think that you will have a problem without building a study........ The extra garage space will be a valuable asset...........and can do double duty.....

I understand wanting to keep the views from as many rooms as possible. However, how much time is spent in the bedrooms? And is the view visible the majority of time one spends in the bedroom? Consider that the most restful, secure sleep is obtained when the bed is placed opposite the entry door. That is not possible in any of your current bedroom layouts. Perhaps you should consider single solid glass French doors or windows flanking the beds opposite the doors rather than the large windows you show on the plan. Choice of doors or windows would be based on accessibility to a deck. I assume bedroom 1 and the office/bedroom have built-in bunk beds. I think the deck between the family and bedroom 3 seems inaccessible and a bit of a waste, and I wonder how one gets outside from the kitchen with the trash, etc. Do you have no plans to garage the vehicles?
